Summary

Product identification

Memtrex KM (MKM) filters are pleated filters constructed with an all-polypropylene design and Veolia's Nylon 66 membrane. They utilize thermoplastic sealing technologies and are individually integrity tested.

Key Features:

• Naturally hydrophilic Nylon 66 membrane
• Non-shedding
• Do not contain leachable wetting agents

Absolute Pore Size Micron Ratings:

• 0.2 µm
• 0.45 µm
• 0.65 µm

Typical Applications:

• Microelectronics ultrapure water filtration
• Filtration of positive photoresists
• Filtration of organic solvents
• General high purity water and strong solvent applications

Materials of Construction

• Media: Nylon 66 Membrane
• Support Layers: Polypropylene Microfiber
• Core and Cage: Polypropylene
• Endcaps and Adapters: Polypropylene

Mechanical / Hydraulic

Dimensions

• Nominal O.D.: 2.75” (70 mm)
• Nominal I.D.: 1.25” (31 mm)
• Effective Filtration Area: 8.0 ft² (0.74 m²)

Operational Limits

• Maximum Forward Differential Pressure: 60 psi (4.1 bar) at 70ºF (21ºC)
• Maximum Reverse Differential Pressure: 30 psi (2.1 bar) at 70ºF (21ºC)
• Maximum Operating Temperature: 180ºF (82ºC) at 10 psid (0.7 bar) in water

Integrity Testing

• 0.2 µm: ≤ 50 cc/min at 30 psig (2.07 bar)
• 0.45 µm: ≤ 50 cc/min at 15 psig (1.03 bar)

Flow Performance in Clean Water

Flow performance data for 10" length filters is presented in a graph format in the original PDF, showing service flow versus pressure drop for different micron ratings (MKM92, MKM94, MKM96). See the official PDF for exact tabulated values and graphs.

Other Specifications

• Sterilization:
  • May be autoclaved or in situ steam sterilized up to 257°F (125°C) in 30-minute cycles, for a maximum accumulated exposure of 10 hours.
  • Can be sanitized with compatible chemical agents.
• Certifications & Compliance:
  • Meets U.S. FDA requirements for food contact under applicable regulations in 21 CFR.
  • Meets the test criteria for USP class VI-121°C Plastics.
• Extractables:
  • Aqueous extracts contain less than 0.25 EU/ml.
  • Typically exhibit low levels of non-volatile residues.
